    摘要: A tape cassette comprises a tape guide having a cylindrical surface formed by hard chromium plating or nickel plating. The tape guide is a cylindrical plate having a slit parallel to the axis. The cylindrical tape guide has a groove at one end of the guide and is fitted to a post having a projection mounted on a half-case under connecting the groove of the guide to the projection of the post to contact the tape with the surface formed by the hard chromium plating or nickel plating.
